Getting great feedback on the forums and plan to drain the current radiator fluid/ water mix to measure how much fluid my system holds. Also going to re-fill with distilled water and Dexcool and do a couple of different test. I did decide to add an adjustable thermostat to give me more control over the fan on temps, currently coming on around 180F. I hard wired it so that the fans continue to run when the car is turned off, only runs for a couple of minutes so no worries on killing the battery
First test: 20min idle time while sitting in the garage with no incoming air. Fan's pulling in air and pushing over the intake and engine. Temp range after heated up was 198~205F. Average coolant temp after warmed up stayed at 200F.
I think I will get better results by reversing the fans to take heat out of the engine compartment. The fans are defiantly pushing some air and I can feel plenty of heat being drawn thru the radiator.
Unfortunately I have business travel in Europe over the next 2 weeks so have to put the project on hold again until I get back.
